Specification of Letters Patent.

Patented June 8, 1920.

Application filed June 23, 1919. Serial No. 306,273.

To all whom it may concern:

Be it known that 1, CHARLES L. BENE- DICT, a subject of the King of England, residin at Toronto, in the county of York, rovince of Ontario, Canada, have invented certain new and useful Improvements in Envelops; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This inventionrelates to improvements in envelops and is especially directed to improving outlook or window-envelops.

The primary object of the invention 1s to provide a construction by which the postage stamp will more effectively adhere to the inclosure and by which air within the inclosure may escape. The purpose of this is twofold, i. 6., to insure that the address on the inclosure will be held in close contact with the envelop window and to permit moisture to escape from a letter which has been press copied.

It has heretofore been proposed to provide envelops with apertures through which postage stamps might project in order to seal to the incl'osure, but with the prior constructions, if the envelop paper is still or thick, said paper will have a tendency to pull the stamp away from the inclosure and consequently the inclosure will be detached from the stamp. Also with the known construction, the trapped air, when the envelop is pressed, had a tendency to move the stamp away from the inclosure.

lBy the present improvements, the portion of the envelop adjacent to the stamp aperture or apertures is slitted, so that the stamp supporting portion may yield independently of the face of the envelop to prevent accidental detachment of the stamp from the inclosure or moisture may escape through the slits. With the improved envelop, the stamp will securely adhere to the inclosure at all times regardless of the stifiness or thickness of the paper, or of the air trapped in the envelop.

The invention consists in the novel features hereinafter described in detail in connection with the accompanying drawing and more particularly pointed out in the appended claims.

Referring to "the drawing Figure 1 is a face view of a window enthe central'portion of a stamp is adapted to project and seal to the inclosure. The face of the envelop is provided with vertical slits 4, one of which is located on each side of the stamp aperture to permit the portion 5 ofthe envelop to. be depressed with the stamp. The portion 5 is of slightly greater width than the ordinary postage stamp 6 and when this portion is depressed in attaching the stamp, air or moisture may escape through the openings provided by the slits.

In Figs. 2 and 3, the face of the envelop has two stamp apertures 10 and horizontal slits 11 located above and below the apertures. In this instance, the portion 12 which contains the apertures, is of slightly greater depth than the ordinary postage stamp and one or two stamps may be sealed through the apertures to the inclosure.

From the foregoing, it is believed that the operation will be readily understood without further description.

I am aware that various changes may be made in the constructions illustrated with out departing from the spirit of the invention as set forth in the following claims.

What I claim and desire to secure by Letters Patent is 1. An envelop having an aperture throu h which a postage stamp is adapted to a sealed to an inclosure, the envelop being provided adjacent to the aperture with a plurality of slits to provide a stamp supporting portion; which may be depressed independently of the remainder of the envelop, and whereby the stamp supporting portion may yield independently of the face of the envelop to prevent accidental detachment of the stamp from the inclosure.

2. An envelop having one of its faces provided with a window through which the address on an inclosure may be exmainder of the apertured face of the enhibited, said face having an aperture velop, whereby the stamp supporting porthrough which a postage stamp is adapted -'-tion may yield independently of the face of 10 to be sealed to the inclosure, the envelop the envelop to prevent accidental detach- 5 being slitted adjacent to the aperture to ment of the stamp from the'inclosure.

provide a stamp supporting portion, which In testimony whereof I afiix my signature. may be depressed independently of the re- CHARLES L. BENEDICT.
